Sexed semen's the future

Peter Allen (Letters, 5 March) is right to question the fate of male calves from the dairy herd. The problem with sexed semen is that it is very new technology and has not really had time to be taken up properly. I can assure him that it will, as the problem of dairy bull calves is an old one stretching back to the days of Ayrshire cows whose male offspring were as worthless in the market place as modern Holsteins. There is also a little ambivalence on the side of the organic certification bodies about sexed semen which has yet to be resolved.
